Neuronal oscillations are generated at many spatial and temporal scales of neuronal organization, and thought to provide a network-level mechanism for the coordination of spatio-temporally distributed spiking activity. For an adequate understanding of quantitative changes in neurophysiological signals, such as electroencephalography (EEG) or magnetoencephalography (MEG), as a consequence of disease, experimental manipulations, or genetic variability there is a need to apply multiple biomarker algorithms.

The Neurophysiological Biomarker Toolbox (NBT) is an open source Matlab toolbox for the computation and analysis of neurophysiological biomarkers (Quantitative electroencephalography (qEEG)). NBT offers an EEG analysis pipeline from data storage to statistics including artefact rejection, signal visualization, biomarker computation, statistical testing, machine learning, and biomarker databasing. NBT allows for easy implementation of new biomarkers, and incorporates an online wiki (this website) that facilitates collaboration among NBT users including extensive help and tutorials. The standardised way of data storage and analysis that NBT proposes will allow different research projects to merge, compare or share their data and EEG biomarker algorithms. The NBT toolbox also makes it easy to integrate questionaire data or cognitive scores.

The NBT is specialized in that it provides a systematic, efficient, and exhaustive characterization of information in recordings of ongoing neuronal oscillations based on a variety of biomarker algorithms.

NBT is both a standard M/EEG toolbox, with support of basic pre-processing features and strong integration with EEGLAB, but also a unique toolbox for the statistical analysis of biomarkers. The NBT toolbox includes machine learning tools for data-mining large sets of biomarkers.

NBT is specialized in analyzing electroencephalography (EEG) and Magnetoencephalography (MEG) data, however it allows the processing of any kind of signal. NBT is mainly focused on statistical analysis of data from clinical research. Typical problems that the NBT will help you solve, are to identify and quantify differences in ongoing neuronal activity between:
